One piece of advice I got from a seasoned mom when I was just starting out was that it wasn't worth the energy and grief to worry about how irreparably scraggly I looked all the time. Instead, she counseled, I should pick one small thing about my appearance that was always well controlled. Hers was her nails. Even when she had a toddler and infant twins, she worked hard to make that sure her nails were done to her liking all the time.
I am very low maintenance in terms of personal grooming, which you know if you've seen me, but this still struck me as good advice. Nails aren't a huge concern to me, but eyebrows are. Or, more accurately, eyebrow is. Maintaining my eyebrow (hereinafter "eyebrows") is not just a matter of personal dignity, but public courtesy. I have pallid skin and dark hair which is committed to concentrating its growth efforts just behind my glasses. If there were an eyebrow subsidiary to Locks of Love, I'd be their star donor. To give my eyebrows free rein is simply antisocial. So whenever I've got a crew in the bath, I clean the bathroom and then get those caterpillars under control. Voila! I've taken time for my appearance like an actual woman and made the world a better place.
Find a thing, girls. If it can help even a trainwreck of feminine aspect like me, it will surely be of value to you.
It just doesn't work for all of us.
